FIELD OF THE TECHNOLOGY

The present technology relates generally to surgical cutting apparatus,and more particularly to, surgical instruments for performingosteotomies.

BACKGROUND

Surgical cutting instruments come in many shapes and sizes. Inperforming an osteotomy with a single-sided device, the user (e.g., aphysician, surgeon, etc.) is often required to perform multiple cutsand/or passes to achieve a desired shape and/or osteotomy. Further,multiple cuts and/or passes with using a surgical instrument can resultin inconsistencies in shape and/or size of the resulting osteotomy indifferent patients. In other words, it takes more time to perform aosteotomy than is otherwise needed and/or there is a degree ofinconsistency and/or inaccuracy when a traditional surgical instrumentis utilized to perform an osteotomy.

SUMMARY

Various embodiments provide surgical instruments and methods forperforming an osteotomy. A surgical instrument includes a body with adistal end, a proximal end, a first surface, and a second surface. Thesurgical instrument can include cutting burrs positioned on the firstsurface and/or the second surface. The surgical instrument can includecutting burrs positioned on the first surface and cutting bladespositioned on the second surface.
